What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if Isatuximab, a monoclonal antibody, can improve kidney function in individuals with Monoclonal Gammopathy of Renal Significance (MGRS), a condition affecting the kidneys. While Isatuximab is already used for multiple myeloma, its use for MGRS remains investigational. Participants must have a confirmed type of MGRS, such as specific kidney inflammation or protein build-up, and exhibit significant protein in their urine. As a Phase 2 trial, this research measures Isatuximab's effectiveness in an initial, smaller group, allowing participants to contribute to significant advancements in MGRS treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but there is a required 'washout' period (time without taking certain medications) of 12 weeks for chemotherapy-based therapies and 24 weeks for Rituximab-based therapies before starting the trial.

Is there any evidence suggesting that Isatuximab is likely to be safe for humans?

Research has shown that isatuximab is generally well tolerated by patients. In earlier studies, most individuals with monoclonal gammopathy of renal significance (MGRS) experienced manageable side effects. These studies did not identify any major safety issues. Additionally, the FDA has already approved isatuximab for treating multiple myeloma, indicating that its safety profile is well understood. However, isatuximab is still under investigation for use in MGRS, so further research is ongoing in this area. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for monoclonal gammopathy, which typically include medications like corticosteroids and chemotherapy, Isatuximab offers a novel approach by targeting CD38, a protein commonly found on the surface of abnormal plasma cells. This mechanism allows Isatuximab to directly attack and eliminate these problematic cells. Researchers are excited about this treatment because it provides a more targeted and potentially less toxic alternative, which might lead to better outcomes with fewer side effects.

What evidence suggests that Isatuximab might be an effective treatment for MGRS?

Research has shown that Isatuximab, which participants in this trial will receive, may help treat monoclonal gammopathy of renal significance (MGRS). In one study, 87% of patients experienced improved kidney function, with some fully or partially recovering. Another study found that 83% of participants saw better kidney function, with many experiencing a significant reduction in disease signs. Isatuximab is already approved for treating multiple myeloma, a related condition, demonstrating its effectiveness. Overall, these studies suggest that Isatuximab could be a promising option for improving kidney health in MGRS patients. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Adults over 18 with MGRS, a kidney condition linked to abnormal proteins in the blood. They should have a life expectancy over 6 months, be relatively active (ECOG ≤2), and have normal organ/marrow function. Those previously treated for MGRS can join if they haven't used CD38 antibody therapy or had certain treatments within the last 3-6 months.

Inclusion Criteria

I have a kidney condition diagnosed through a biopsy, related to abnormal protein deposits.

Estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2.

Exclusion Criteria

I have been diagnosed with Multiple Myeloma, high-risk smoldering Multiple Myeloma, or a B cell lymphoma that requires treatment.

Participants who are receiving any other investigational agents concurrently.

I haven't had chemotherapy in the last 12 weeks or Rituximab in the last 24 weeks.

What Are the Treatments Tested in This Trial?

Interventions

• Isatuximab

Trial Overview The trial is testing Isatuximab's effectiveness on improving kidney function in MGRS patients. Although FDA-approved for multiple myeloma, its use here is investigational as it's not yet approved for treating MGRS.

How Is the Trial Designed?

Group I: Isatuximab for MGRS Experimental Treatment 1 Intervention

Subjects will receive Isatuximab for 6 months and will be followed for an additional one year post therapy for outcome follow-up.

Isatuximab is already approved in European Union, United States for the following indications:

Approved in European Union as Sarclisa for:

• Multiple myeloma

Approved in United States as Sarclisa for:

• Multiple myeloma in combination with pomalidomide and dexamethasone for adults who have received at least two prior therapies including lenalidomide and a proteasome inhibitor
• Multiple myeloma in combination with carfilzomib and dexamethasone for adults with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy
• Newly diagnosed multiple myeloma in combination with bortezomib, lenalidomide, and dexamethasone for adults who are not eligible for autologous stem cell transplant

Published Research Related to This Trial

Isatuximab monotherapy was found to be well tolerated and effective in Japanese patients with relapsed/refractory multiple myeloma, with an overall response rate of 36.4% and a clinical benefit rate of 54.5%.

The study identified a recommended dose of 20 mg/kg administered weekly and bi-weekly, with a median progression-free survival of 5.6 months, indicating promising antitumor activity and an acceptable safety profile.

In a phase 3 study involving 307 patients with relapsed and refractory multiple myeloma, the combination of isatuximab, pomalidomide, and dexamethasone significantly improved progression-free survival (11.5 months) compared to pomalidomide and dexamethasone alone (6.5 months).

The most common side effects included infusion reactions and upper respiratory infections, with a low incidence of treatment-related deaths, indicating that isatuximab is a relatively safe and effective treatment option for patients who have not responded to other therapies.

Isatuximab, a monoclonal antibody targeting CD38, was shown to significantly improve progression-free survival in adult patients with relapsed and refractory multiple myeloma when used in combination with pomalidomide and dexamethasone, compared to pomalidomide plus dexamethasone alone.

While treatment with isatuximab was associated with a higher incidence of treatment-related adverse events, including serious complications, the overall safety profile was deemed acceptable, leading to a positive benefit-risk ratio for its use in this patient population.

Isatuximab, a monoclonal antibody targeting CD38, has been studied in 476 multiple myeloma patients and shows a two-compartment pharmacokinetic model, indicating its complex behavior in the body, especially in patients with different types of immunoglobulin.

Patients with IgG M-protein had lower drug exposure, but no dose adjustments were necessary as the efficacy and safety profiles remained consistent across different immunoglobulin types, suggesting that isatuximab's effectiveness is robust regardless of the patient's specific disease characteristics.
